ACA Subsidy Changes 2026: What Early Retirees Must Know

For Americans who retired before age 65 and are not yet eligible for Medicare, the ACA Health Insurance Marketplace has served as a critical safety net. And for the past several years, that safety net has been unusually generous. The American Rescue Plan Act of 2021 (ARPA) dramatically expanded premium tax credits, temporarily eliminating the income cap that previously cut off subsidies at 400% of the Federal Poverty Level (FPL). A follow-on extension through the Inflation Reduction Act kept those enhanced credits in place through 2025.

But as of this writing, those enhancements are scheduled to expire on December 31, 2025. That means 2026 marketplace coverage - the plans you select during fall 2025 open enrollment - would revert to the pre-2021 subsidy structure unless Congress acts. For many early retirees, the financial impact could be substantial. Understanding what is changing, why it matters, and what income planning options are commonly discussed can help you approach open enrollment with much greater clarity.

To understand the 2026 changes, it helps to see what the enhanced premium tax credits actually changed since 2021. Under the original ACA subsidy rules, premium tax credits were available to households with income between 100% and 400% of the FPL. In 2025, 400% FPL equals approximately $58,320 for a single person and $79,080 for a couple (based on 2025 FPL figures published by the U.S. Department of Health and Human Services). Above that threshold, no subsidy was available, regardless of how much premiums cost.

The ARPA changes did two important things:

• Removed the 400% FPL income cap entirely, so higher-income households could still receive some subsidy if their premiums were high relative to income.
• Capped the percentage of income that enrollees pay for the benchmark Silver plan at no more than 8.5% of household income at all income levels, compared to a sliding scale that reached 9.83% under pre-ARPA rules (the exact cap percentage is adjusted annually by the IRS).

If these enhancements expire as currently scheduled, the 2026 subsidy structure reverts to the pre-2021 rules. That means the 400% FPL ceiling returns, and households earning above that threshold would receive no premium tax credit at all - even if they are paying thousands of dollars per month for coverage.

According to KFF (formerly the Kaiser Family Foundation), millions of marketplace enrollees have benefited from the enhanced subsidies since 2021, with a meaningful share of those enrollees having incomes above 400% FPL. The expiration would disproportionately affect early retirees, who often have moderately high income from portfolio withdrawals but no employer coverage and no Medicare eligibility.

The phrase subsidy cliff describes what happens under the original ACA rules when a household's income crosses 400% FPL. Unlike a gradual phase-out, the old system worked as an on/off switch: one dollar above the threshold eliminated the entire credit. This created a situation where earning slightly more could result in thousands of dollars in higher net health insurance costs for the year.

Early retirees are uniquely vulnerable to this dynamic for several reasons:

• Their income is often flexible - coming from portfolio withdrawals, Roth conversions, Social Security, and capital gains rather than a fixed paycheck.
• They have years or even decades before Medicare eligibility at 65, so marketplace premiums are a major budget line item.
• Premiums for people in their late 50s and early 60s are significantly higher than for younger enrollees, making the dollar value of subsidies much larger.

To illustrate the stakes, consider a hypothetical scenario. Imagine a 58-year-old single early retiree in a mid-cost market. Under the enhanced rules, if their MAGI is $65,000 (above 400% FPL), they might still receive a meaningful premium tax credit because their benchmark Silver plan premium exceeds 8.5% of their income. If the enhanced rules expire and their MAGI remains at $65,000, that credit disappears entirely. Depending on the market and plan chosen, this could translate to several thousand dollars more per year in premium costs. This is a hypothetical illustration only and not a projection of any specific individual's costs; actual amounts vary widely by location, plan, age, and household size.

For early retirees already watching their withdrawal rate carefully, this kind of shift is worth planning around well in advance. Our deeper look at managing healthcare costs before Medicare covers the full landscape of options in this critical gap period.

ACA subsidy eligibility is based on Modified Adjusted Gross Income (MAGI), which for most people is close to their Adjusted Gross Income (AGI) from their federal tax return, with a few specific add-backs. Understanding what counts toward ACA MAGI is essential for early retirees managing their income:

• Taxable Social Security benefits count toward MAGI.
• Traditional IRA and 401(k) withdrawals count in full as ordinary income.
• Roth IRA withdrawals do not count toward MAGI (provided the distribution rules are met), which is a key reason Roth accounts are frequently discussed in this context.
• Realized capital gains from taxable brokerage accounts count toward MAGI, including long-term gains.
• Dividends and interest from taxable accounts count toward MAGI.
• Roth conversion amounts count as ordinary income in the year of conversion.

This income composition gives early retirees with diversified accounts a meaningful degree of control - but navigating those trade-offs involves complexity that extends well beyond any single variable. A tax professional or financial adviser can help model the interactions between subsidy eligibility, income tax brackets, and long-term portfolio strategy.

Because MAGI is so central to subsidy eligibility, many early retirees and financial planners discuss income management as part of a broader healthcare cost strategy. The following approaches are commonly explored - though whether any of them is appropriate in a given situation depends on factors specific to that individual's full financial picture.

1. Drawing from Roth accounts strategically

Qualified Roth IRA distributions do not count toward ACA MAGI. For early retirees who have built up Roth balances - either through direct contributions or prior Roth conversions - drawing primarily from those accounts in years when subsidy eligibility is a priority is one approach that comes up frequently in planning conversations. The trade-off is that Roth assets may also be valuable later for managing Medicare's IRMAA surcharges or required minimum distributions, so the long-term picture matters. See how Roth conversions interact with Medicare costs later in retirement for context on those downstream effects.

2. Timing capital gains realizations

Early retirees with taxable brokerage accounts often have some flexibility over when they realize capital gains. Spreading gains across multiple years rather than concentrating them in a single year can help keep MAGI more predictable and within subsidy-eligible ranges. Notably, in years when income is lower, early retirees may also have the opportunity to harvest gains at the 0% federal long-term capital gains rate, which applies up to certain taxable income thresholds. Our article on the 0% capital gains bracket explains how that threshold works in detail.

3. Roth conversion planning in lower-income years

Roth conversions increase MAGI in the year they occur, which can push income above subsidy thresholds. However, some early retirees find value in doing modest conversions in years when their income is already near the ceiling anyway, or when the long-term tax benefit outweighs the short-term subsidy cost. This involves a genuine trade-off that is difficult to generalize - which is precisely why detailed modeling with a tax-aware financial planner tends to be the most useful approach.

4. Managing retirement account withdrawal sequencing

The order in which early retirees draw from different account types - traditional pre-tax accounts, Roth accounts, and taxable brokerage accounts - has a direct effect on annual MAGI. This sequencing decision is one of the more consequential planning choices for the early retirement years.

A calculator example (illustrative only)

To make this concrete, consider a hypothetical couple, ages 60 and 58, who retired early. Their annual expenses are $80,000. In a given year, they plan to fund those expenses entirely from traditional IRA withdrawals. At 2025 FPL levels, 400% FPL for a household of two is approximately $79,080. Their $80,000 withdrawal would put them just above 400% FPL, and if the enhanced credits expire, they would receive no subsidy.

If instead they fund $40,000 from Roth accounts (which do not count toward MAGI) and $40,000 from traditional IRA withdrawals, their MAGI drops to $40,000 - well below 400% FPL - and significant subsidy eligibility could be preserved. Again, this is a simplified illustration only. Real outcomes depend on many variables including tax filing status, specific plan premiums, state of residence, and the final 2026 FPL figures when published.

As of mid-2025, the expiration of enhanced ACA subsidies after December 31, 2025 remains the current legal default. Congress has the ability to extend or modify these provisions, as it has done before, but no extension has been enacted as of this writing. Early retirees relying on marketplace coverage have good reason to monitor legislative developments through fall 2025, while also planning for the possibility that the enhanced credits do not continue.

A few practical considerations worth being aware of as you approach this period:

• Open enrollment for 2026 coverage typically runs from November 1 through January 15. Decisions made during this window will determine your 2026 plan and premium costs.
• Subsidies are based on projected annual income. When you enroll, you estimate your expected MAGI for the coverage year. If your actual income differs from the estimate, you reconcile the difference on your tax return - which can result in either a refund or a repayment obligation.
• Healthcare.gov and state marketplace websites provide plan comparison tools and subsidy estimators that are updated annually. The IRS also publishes guidance on premium tax credit eligibility each year.
• Your 2024 and 2025 tax returns will be useful inputs for estimating your 2026 MAGI, though any planned changes to your withdrawal strategy could shift that figure materially.

The interaction between ACA subsidies, Roth conversions, capital gains timing, and longer-term Medicare cost planning is genuinely complex. Getting a handle on your total projected healthcare costs across the full retirement timeline - not just the early years - can be a valuable exercise. Our guide to estimating total healthcare costs in retirement provides a useful framework for thinking through that bigger picture.
